As Time magazine and a number of other sources noted earlier today:
Donald Trump pulled out all the stops courting coal miners in West Virginia Thursday night, but he told them to skip voting in the primary.
“Now what I want you to do is save your vote,” Trump told the crowd in Charleston, West Virginia. “You know, you don’t have to vote anymore. Save your vote for the general election, OK? Forget this one, the primary is gone.”
Somebody must have gotten to Trump, CBS News later reported that he used his Twitter feed a few hours later to urge supporters to vote.
